InVista™ Technology Origin
Targeting Unpiggable and Difficult Pipelines
• Industry consensus estimates
30-40% of the world’s pipelines
are classified as ―unpiggable.‖
• At least another 10% of the
piggable pipelines are so called
―difficult‖ pipelines.

InVista™ Ultrasonic Inline Inspection
InVista™ provides:
• High-fidelity ultrasonic inline inspection of
unpiggable and difficult pipelines 3‖ (75mm) –
14‖ (355mm) in diameter
• Combined absolute wall loss and full
geometry dimensions in a single pass
• Circumferential, longitudinal and ID/OD
location of defects with referencing
• High-density direct measurement ultrasonic
technology provides accurate, repeatable
results measured to 0.005‖ (0.127mm)
precision & 0.030‖ (0.762mm) remaining wall
InVista™ Advantages
• The term ―high-fidelity‖ refers to the
reproduction of sound and images with
minimal distortion. Less distortion means
superior, more accurate data.
• Signal distortion and other noise effects can
reduce the ILI tool’s ability to fully
discriminate and properly size pipeline flaws,
thereby exposing you to increased risk.
• By design, InVista™ is not subject to the
same noise effects associated with
movement, pipeline disturbances and related
wear challenges as conventional tools.
• Our advanced approach produces the
highest quality images available in the
industry today.
InVista™ High-Fidelity Approach
InVista™ Benefits

Reduced Operational Risk
• Unique design reduces wear effects and minimizes tool
impacts compared with conventional ILI tools.
• Solutions oriented—analysis of all line data vs. individual
boxed flaw locations.
Cost-Effectiveness
• Linear UT sizing minimizes verification digs and improves
excavation and repair confidence.
• Permanent line modifications are not required.
Time Efficiency

• Significant wall-thickness variations
• Single entry/exit, line stoppage, plugged valves
• Unbarred tees and wyes
Case Study 1 - Requirements
Louisiana USA
This 4‖ (100mm) line
develops a leak and
regulators mandate that
the line be taken out of
service and inspected for
repair.
Adding to the operator's
sense of urgency was the
fact the crude was selling
around $130 per barrel.
“We need this pipelineback in service ASAP…”
InVista™ is Successful
Launcher
• Minimal working area
• Minimal trap length
• Unbarred 6‖ x 6‖ (150mm)
tee at 6 o’clock
Receiver
• Minimal nominal pipe after
valve
• Minimal trap length
• Line was not properly
cleaned prior to ILI
• 7 major corrosion and pitting flaws detected
• Client verified each flaw with alternate manual NDT method (i.e. pit gauge and/or manual ultrasonic scope)
• Repairs were made to all areas based upon InVistaTM
inspection results

Case Study 2 - Requirements
California USA
Major client received an
allotted budget to upgrade
and make piggable all
regulated assets.
After meeting with Quest this
Operator realized it could
inspect these lines for a
small fraction of its entire
budget.
“We do not want to spend
the money to modify our
pipelines unless it is
absolutely needed…”
InVista™ is Successful
Pipeline Details
•Same location for both launch and receive using client-owned 14‖ barrel.
•Multi-diameter pipeline was easily inspected using two tools at client’s request:
1. Ran 8‖ (200mm) tool to 6‖ (150mm) reducer and back out.
2. Ran 6‖ tool through 8‖ line, through 6‖ and back out.
•Inspected over 1 mile of pipe below city streets with limited access.
•No prior inspection due to tight bends, unbarred tee and plug valves
•Legacy line—no original drawings
External flaw at 688 feet
• Length = 1.0 in (25.4mm)
• Width = 0.25 in (6mm)
• Depth = 0.122 in (3.1mm)
• 39% wall loss
RSF = 0.699
MAOPr = 1001 psi (69.03 bar)
B31G = 1415.3 (97.6 bar)

Case Study 3 - Requirements
Alaska USA
Major client had problems
with conventional ILI tools
becoming stuck repeatedly
and needed a solution.
Compounding issues: these
pipelines contained cased
crossings and there were
minimal traps with limited
space availability.
“We cannot risk getting
another pig stuck because
it will shut down our entire
operation…”
InVista™ is Successful
Pipeline Details
•Two 6‖ (150mm) produced water pipelines tied together for approximately 7 miles
•Pipeline pressure 1500 PSI (103.4bar) and 150 degrees
•No prior inspection due to limited trap lengths--No modifications required for InVista
•Launcher reduced from 12‖ (305mm) to 10‖ (250mm) to 8‖ (200mm) then to 6‖
(150mm) nominal in one instance
•Insulated pipe could normally be inspected with manual UT, but this was >100 ft
(33M) from the ground.

5. Conclusion
Historical Assessment Methods
•Conventional ILI tools are more demanding on operator and less capable than InVista™ single tool packaged solution.
•MFL is subject to secondary influences which can mask important components of the signal affecting detection and sizing of defects.
Conventional ILI
(includes tethered & BIDI)
•Direct Assessment is subjective and only incorporates snapshots of your asset.
•Compare time required for capturing and assimilating field data and decisions based on presumptions against running a tool in 1 day with quantitative report prepared by specialists delivered in about 30 days.
Direct Assessment
(includes guided wave & localized UT)
•Hydrostatic testing does not deliver value—bursting pipe and increasing failure risk for other locations; does not properly mitigate risk, improve pipeline integrity, or otherwise provide actionable information.
•Operational constraints and limited operator assurance is not sufficient trade-off for reliable, accurate direct pipeline assessment.

Consequence of Tolerance
UT Inspection → higher return
on investment because of
accuracy driven efficiencies.
The magnitude of your rehabilitation and repair
work is greatly affected by tool tolerances. ―The
best tolerances result in the least repairs, which
means money saved in the repair program.”
Choosing to run tools with better tolerances
increases your efficiencies and decreases waste,
allowing more effective decision-making.
The higher accuracy and confidence that
InVista™ offers increases your profitability,
maximizes limited resources, and results in more
effective risk mitigation when compared with MFL
tools.
